Description

This 400GBASE-2FR4 OSFP optical transceiver delivers 400G over two pairs of duplex single-mode fibre (G.652) at distances up to 2km, using dual duplex CS connectors. It breaks out to 2 x 200G and interoperates with 2 x 200GBASE-FR4 optics, making it suited to high-density data centre and spine-leaf deployments that need flexible 400G and 200G connectivity. CWDM wavelengths, 50G PAM-4 optical lanes and digital optical monitoring support reliable, monitorable links.
